Co-Zn alloy coating was prepared via electrodeposition in choline chloride- urea ionic liquid. The effects of cathode potential, concentration ratio of Co(Ⅱ)- to Zn(Ⅱ), temperature and deposition time on the elec-tredeposition behavior were investigated, and the properties of the alloy coating were also analyzed. Results indicate that uniform amorphous Co-Zn alloy coating with metallic luster and good ad-hesion to substrate can be readily obtained by properly adjusting the composition of the choline chloride-urea ionic liquid and elec-trodeposition parameters as well, and the Co content can reach 90% ( mass fraction).
